There are three problems with artwork NFTs at the moment:
the buyer isn't getting much more than a row in a database,
sales are linear and infrequent, so there is no liquidity, and hence price discovery is speculative rather than investment or trade-driven, and
ongoing royalties are difficult to implementThrough the use of capped Automated Market Makers and an interesting token-to-license path, Vitomir Jevremovic is aiming to solve all of those problems in one go.
In this video, I talk about the mechanism he is proposing.
(Full disclosure: I hold no tokens or equity in the NFT-PRO project.)
